Use VCSEC broadcasts for Teslemetry vehicle covers

[Bre77]

Breaking change

Proposed change

Reroute the charge-port door, front trunk, and rear trunk covers to the vehicle's
own VCSEC closure broadcasts when it is BLE paired, reusing the BLE data manager's
connection-generation availability. Open/close commands still route through the
existing command router. Windows stay on the stream and the sunroof is unchanged.
Unknown closure enums resolve to unavailable rather than a false state.

This stacks on #977 (its base branch), the binary-sensor PR that adds the BLE
data manager, and is part of the series moving cheapest-source vehicle values
onto the local Bluetooth link.
